Ib array yog a cov ntaub ntawv homogeneous qauv (cov ntsiab lus muaj tib yam cov ntaub ntawv hom) uas khaws cov khoom sib txuas ua ke ntawm cov khoom sib txuas ua ke - faib rau hauv kev nco sib txuas. Txhua yam khoom ntawm lub array tuaj yeem nkag tau los ntawm kev siv nws tus lej (piv txwv li, index). Thaum koj tshaj tawm ib array , koj teem nws loj.
Tsis tas li ntawd, vim li cas ib qho array hu ua homogeneous sau cov ntaub ntawv hauv Java?
Hauv Java , ib array yog homogeneous , i.e. tag nrho nws cov hlwb muaj cov ntsiab lus ntawm tib hom. Yog li ntawd, ib array ntawm integers tsuas muaj integers (int), ib array ntawm cov hlua - tsuas yog cov hlua, thiab ib qho array ntawm qhov piv txwv ntawm chav kawm Dog uas peb tau tsim yuav tsuas muaj cov khoom Dog xwb.
Tsis tas li ntawd, cov ntaub ntawv ntawm cov ntsiab lus ntawm ib qho array hu ua dab tsi? Hauv computer science, ib hom array yog a hom ntaub ntawv uas sawv cev rau ib phau ntawm cov ntsiab lus ( tus nqi los yog variables), txhua tus xaiv los ntawm ib lossis ntau qhov ntsuas (txhais tus yuam sij) uas tuaj yeem suav tau thaum lub sijhawm ua haujlwm thaum lub sijhawm ua haujlwm. Xws li ib qho kev sau feem ntau yog hu ua ib array sib txawv , array tus nqi, los yog yooj yim array.
Tsis tas li ntawd, cov ntaub ntawv homogeneous yog dab tsi?
Homogeneous cov ntaub ntawv qauv yog cov cov qauv uas tsuas muaj hom zoo sib xws cov ntaub ntawv . EXAMPLE: zoo li a cov ntaub ntawv qauv uas tsuas yog ntab thiab cov lej suav xwb. Ib qho piv txwv yooj yim yog ib qho array. Heterogeneous cov ntaub ntawv qauv yog cov cov qauv uas muaj ntau hom lossis hom sib txawv cov ntaub ntawv.
Heterogeneous array yog dab tsi?
A heterogeneous array yog ib array ntawm cov khoom uas txawv hauv lawv cov chav kawm tshwj xeeb, tab sis tag nrho yog muab los ntawm lossis yog piv txwv ntawm cov chav kawm hauv paus.

Vim li cas cov ntaub ntawv tiaj tus tsis zoo dua li cov ntaub ntawv sib raug zoo?
Ib lub rooj ua ntaub ntawv tiaj tus yog qhov tseem ceeb rau kev sau cov ntaub ntawv tsawg. Tab sis cov ntaub ntawv loj loj tuaj yeem ua tsis tau raws li nws siv ntau qhov chaw thiab nco dua li cov ntaub ntawv sib txheeb. Nws kuj yuav tsum tau muab cov ntaub ntawv tshiab ntxiv txhua zaus koj nkag mus rau cov ntaub ntawv tshiab, qhov kev sib raug zoo database tsis
Dab tsi yog qhov sib txawv ntawm cov ntaub ntawv sib sau ua ke thiab cov ntaub ntawv tsis sib xws?
Kev sib sau cov ntaub ntawv yog sau thiab sau cov ntaub ntawv; kom disaggregate cov ntaub ntawv yog rhuav tshem cov ntaub ntawv sib sau ua ke rau hauv cov khoom siv lossis cov ntaub ntawv me me
Dab tsi yog lub hom phiaj ntawm delimiters nyob rau hauv cov ntawv sau npe ob hom ntawv cov ntaub ntawv delimiters?
Cov ntaub ntawv delimited yog cov ntawv nyeem siv los khaws cov ntaub ntawv, uas txhua kab sawv cev rau ib phau ntawv, tuam txhab, lossis lwm yam, thiab txhua kab muaj cov teb sib cais los ntawm tus lej
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Vim li cas cov ntaub ntawv zoo tseem ceeb heev rau kev sau cov ntaub ntawv txheeb cais?
Cov ntaub ntawv muaj txiaj ntsig zoo yuav ua kom muaj txiaj ntsig ntau dua hauv kev tsav lub tuam txhab kev vam meej vim yog kev vam khom ntawm qhov tseeb-raws li kev txiav txim siab, tsis yog kev coj cwj pwm lossis tib neeg kev xav. Ua kom tiav: Xyuas kom tsis muaj qhov khoob ntawm cov ntaub ntawv los ntawm qhov yuav tsum tau sau thiab qhov twg tau sau tiag
